The two men accused of killing three black people and wounding two others in shootings that terrified this city over the Easter weekend confessed to the police shortly after their arrest Sunday morning, the authorities said on Monday.

The men — Jacob C. England, 19, and Alvin L. Watts, 32 — were arrested after a series of shootings on Friday that city and community leaders believe were racially motivated attacks. Mr. England and Mr. Watts randomly shot pedestrians and residents as they drove a pickup truck through the predominantly black neighborhoods of north Tulsa, the authorities said.
